Summary: Monitoring tree physiological responses to drought using drone-based remote sensing and PRI revealed that non-irrigated trees showed higher stress levels compared to irrigated trees. Long-term acclimation influenced the seasonal relationship between PRI and soil water availability. This study demonstrates the importance of remote sensing techniques in scaling tree responses to drought stress and the persistence of legacy effects even after irrigation cessation.

Summary: Expression of VPZ genes in potato plants accelerates the induction and relaxation of photoprotection under various light conditions but does not improve photosynthetic rate or plant growth. Instead, tuber yield decreases under fluctuating light conditions. The negative effect may be due to reduced radiation use efficiency caused by strong NPQ induction under high light conditions.

Summary: The Photochemical Reflectance Index (PRI) is an optical indicator of photosynthetic light-use efficiency, photoprotection, and stress in plants. However, its interpretation depends on irradiance, which is difficult to obtain from remote sensing imagery. In this study, we developed a framework for modeling and interpreting PRI-light responses using airborne imaging spectrometry and forest inventory data. Our findings show that tree photoprotective strategies can be quantified using airborne hyperspectral data in complex forests.

Summary: This study found that crop residue inputs can increase soil organic carbon, nitrogen, and phosphorus contents, helping to alleviate soil carbon limitation and maintain balanced soil stoichiometry. The increase in soil organic carbon and carbon-to-nitrogen (phosphorus) ratio reached saturation after around 13-16 years, while the increase in grain yield stopped. A predictive model was proposed to evaluate the potential for crop residue improvement under different soil conditions and nitrogen input levels.

Summary: Soil enzymes play a crucial role in mediating ecosystems' responses to environmental drivers. Understanding their sensitivity to global change drivers can help predict future scenarios and design tailored interventions. However, assessing the interactions between different drivers remains a challenge, as the direct, indirect, and combined effects need to be disentangled. This review examines the effects of global change drivers on soil enzyme activities and identifies knowledge gaps and challenges for future research and biomanipulation techniques. The overall increase in soil enzyme activities and biogeochemical cycles will continue, but factors like shifts in microbial communities and changes in carbon use efficiency can cause inflection points.

Summary: The unprecedented warming in recent decades has led to delayed autumn leaf senescence dates in the Northern Hemisphere. This study shows that changes in soil moisture have a significant impact on autumn leaf senescence, surpassing the effects of temperature, precipitation, and radiation. A new model, CDDSM, based on soil-moisture-constrained cooling degree days, outperforms other models in predicting leaf senescence dates, especially in arid and semi-arid regions. The study also reveals that predicted leaf senescence dates under future climate change scenarios are earlier than other models.

Summary: The stability of ANPP in alpine meadow is affected by precipitation fluctuations, especially extreme precipitation. Normal interannual fluctuations in precipitation and recent changes in regional precipitation have little effect on ANPP stability, but extreme precipitation significantly reduces ANPP, species asynchrony, and ANPP stability. ANPP stability is directly influenced by population stability, species asynchrony, and grass stability, while the effect of species diversity on ANPP stability depends on its impact on species asynchrony and population stability. Dominant species stability indirectly affects ANPP stability by altering species asynchrony.

Summary: Soil nutrient availability and functional traits interact in complex ways during the assembly of tree communities, with strong associations between nutrient concentration and tree species composition. Soil nitrogen concentration has a positive effect on functional space and evenness at the site level, while it negatively affects the functional space not occupied by any species in the tree community. Leaf nitrogen shows evolutionary lability among sister-species pairs, indicating its influence on tropical tree species diversification patterns.

Summary: This study investigates the stoichiometry of carbon (C), nitrogen (N), and phosphorus (P) in fresh and weathered sandstones from Longhushan World Geopark in SE China. The results show that weathering significantly affects the concentrations of C, N, and P, with a decrease in C concentrations and a slight decrease in N concentrations, while P concentrations slightly increase. Microscope observations reveal that fresh sandstones contain calcite, apatite, microplagioclase, and organic matter, while weathered sandstones predominantly consist of apatite and organic matter. The allometric relationships and mineral changes indicate that chemical mechanisms play a significant role in influencing the stoichiometry of C, N, and P in rocks.

Summary: As the awareness of anthropogenic climate change increases, attention is being given to compound extremes, such as co-occurring soil drought and atmospheric aridity, which have disproportionate impacts on natural and societal systems. Few advancements have been made in determining the net effect of human influence on the occurrence of compound extremes. This study shows that anthropogenic forcing weakens the coupling between soil moisture and vapor-pressure deficits, leading to a decrease in the frequency of compound drought and aridity globally. Feedbacks between land and atmosphere strength were found to be primarily influenced by aerosol cooling effects rather than greenhouse gas concentration increases, suggesting that the trade-off between these anthropogenic forcings will determine future patterns of concurrent drought and aridity in a changing climate.

Summary: Precipitation changes have significant impacts on the carbon, nitrogen, and phosphorus cycles in terrestrial ecosystems. This study analyzed a large number of observations from field studies to investigate the effects of increased and decreased precipitation on the stoichiometry of plants, soils, and microorganisms. The results showed that plants were more sensitive to decreased precipitation, while soil microbial communities were more sensitive to increased precipitation. Additionally, soil microorganisms maintained stoichiometric homeostasis, while plants tended to follow the stoichiometry of the soils. These findings highlight the importance of considering specific nutrient allocation strategies of plants and microbial communities in predicting ecosystem functions and carbon cycling under future climate change scenarios.

Summary: Canopies play a crucial role in redistributing nitrogen in forest ecosystems, and not considering their influence can lead to biased estimates of the ecological consequences of human-induced nitrogen deposition. This study investigated the effects of different approaches and levels of nitrogen addition on microbial residual carbon (MRC) accumulation in a tropical forest. Results showed that the response of MRC to nitrogen addition varied with soil depth, with contrasting effects in the topsoil and subsoil. Understory nitrogen addition had greater effects on MRC accumulation compared to canopy nitrogen addition. These findings highlight the important role of canopies in mitigating the impacts of nitrogen deposition on soil carbon cycling in tropical forests and the need for further research on depth-dependent response mechanisms.

Summary: This study investigates the interactive effects of drought and pathogen attack on root exudation in tomato plants. The researchers found that drought increased the exudation of organic carbon and nitrogen, while pathogen attack did not have a significant effect. However, the total exudation per plant remained similar between control and water-limited plants due to the reduction in plant biomass caused by drought. The study highlights the importance of preserving diverse crop cultivars to ensure food security under increasing drought.

Summary: This study demonstrated that co-expressing two exogenous genes, tfdB and bphC, in Arabidopsis thaliana improved the tolerance and removal efficiency of PCB28. Transgenic plants also exhibited increased enzymatic activities under PCB28 stress. The co-expression of tfdB and bphC in A. thaliana resulted in nearly twofold increase in PCB28 removal rates from soil. This research suggests that co-expressing two genes holds great potential for enhancing phytoremediation efficiency and mitigating PCB-induced toxicity stress on plants.

Summary: In eukaryotic cells, epigenetic modifications of DNA and histones play a crucial role in gene expression regulation. ROXY19, a plant-specific CC-type glutaredoxin, was found to strongly repress a subset of genes regulated by class II TGA factors through its association with the TPL/TPR family. The ectopic expression of ROXY19 in Arabidopsis plants led to hypersensitivity to xenobiotic chemicals due to the silencing of detoxification pathway genes.

Summary: This study identified and characterized 163 C2H2-type zinc finger proteins in non-heading Chinese cabbage. Two of these proteins, BcZAT12 and BcZAT10, were found to be closely related to cold tolerance and acted as transcriptional repressors in regulating cold resistance. Furthermore, BcZAT12 was shown to directly bind to the promoter of BcCBF1 and inhibit its activity. Additionally, interactions between BcZAT12 and other proteins such as BcABF2/4 were observed. These findings provide insights into the functional roles and regulatory mechanisms of C2H2-ZFPs in non-heading Chinese cabbage under cold stress.

Summary: Soil salinization is a major obstacle for agriculture sustainability, as it severely affects plant growth and crop yield. Ethylene, a stress hormone, plays a crucial role as a signal molecule in coordinating plant growth and stress response in the model plant Arabidopsis. However, the roles and mechanisms of ethylene in most crop plants under salinity remain undefined. This review summarizes the universal roles of ethylene and focuses on its divergent roles in rice and other crop species under salinity, particularly in terms of ethylene biosynthesis and signal transduction. The contradictions between ethylene production and signaling in salt response are also discussed.
